Within a very smelly and obnoxious mixed microbial community, there exists both Ohious statious and Michiganeous wolverenious. If the community contains 10,000,000 M. wolverenious, which can be detected after 30 rounds of PCR amplification of 16S rRNA, how many O. statious are there if it takes 50 rounds of PCR to detect O. statious 16S rRNA in the same smelly microbial community.

a. 100,000
b. 10,000
c. 10
d. 100
e. 1,000
